Beakers, Erlenmeyer flasks, Florence Flasks, graduated cylinders, all used to measure and mix chemicals together to form solutions. Triple-beam balances, pan balances, used to weigh-out chemicals. Centrifuges for separating precipitates/solids from solutions. Infra-red, Ultraviolet, flame, and photometric spectrometers for determining absorption and emission spectra of elements and compounds. Evaporator flasks and distilling columns for concentrating and distilling solutions and recovering/purifying solvents. Gas chromatographs for separating volatile components from solutions and plotting their relative abundances. Liquid chromatography columns for separating and collecting components from dissolved mixtures. Bunsen burners and electric hotplates for heating solutions. Micro-pipettes for precise volumetric measuring and delivering of solutions. In biochemical and biological labs, also polymeric chain-reaction cycling machines for amplifying RNA and DNA. Electric ovens for drying or fusing solid materials, or for incubating bacterial cultures; microscopes
for identifying microbes and organ tissues, measuring blood-cell counts and sperm counts.
